The daemons are doing reverse DNS lookups on the IP addresses and not
getting any answers.

You can either tweak that in the resolv.conf file so it doesn't take
so long to give up (see the man page for options) or configure your
services to ignore it.

For sshd you just need to uncomment the following line in sshd.conf:

#UseDns no

 But I don't see anything wrong with how things are happening in this situation.
